GENERAL NOTES:

(a) For temperature limitations, see notes in Tables II-2-1.1 through II-2-3.17 of Mandatory Appendix II.

(b) Plate materials are listed only for use as blind flanges and reducing flanges without hubs (see para. 5.1). Additional plate materials

listed in ASME B16.34 may also be used with corresponding B16.34, Standard Class ratings.

NOTE:

(1) ASME Boiler and Pressure Vessel Code, Section II materials may also be used, provided the requirements of the ASME specification are

identical to or more stringent than the corresponding ASTM specification for the Grade, Class, or Type listed.

(a) Cast flanges and flanged fittings shall be markedwith the ASTM specification,2 grade identification sym-bol (letters and numbers), and the melt number or meltidentification.

(b) Plate flanges, forged flanges, and flanged fittingsshall be marked with the ASTM specification numberand grade identification symbol.2

(c) A manufacturer may supplement these mandatorymaterial indications with his trade designation for thematerial grade, but confusion of symbols shall beavoided.

(d) For flanges and flanged fittings manufacturedfrom material that meets the requirements of more thanone specification or grade of a specification listed inTable 1A, see para. 4.2.8.

4.2.3 Rating Designation. The flange or flanged fit-ting shall be marked with the number that correspondsto its pressure rating class designation (i.e., 150, 300,400, 600, 900, 1500, or 2500).

4.2.4 Conformance. The designation B16 or B16.5shall be applied to the flange or flanged fitting, prefera-bly located adjacent to the class designation, to indicate

2 An ASME Boiler and Pressure Vessel Code, Section II specifica-tion number may be substituted for an ASTM specification numberprovided the requirements of the ASME specification are identicalto or more stringent than the ASTM specification for the Grade,Class, or Type of material.

conformance to this Standard. The use of the prefixASME is optional.

4.2.5 Temperature. Temperature markings are notrequired on flanges or flanged fittings; however, ifmarked, the temperature shall be shown with its corres-ponding tabulated pressure rating for the material.

4.2.6 Size. The NPS designation shall be markedon flanges and flanged fittings. Reducing flanges andreducing flanged fittings shall be marked with the appli-cable NPS designations as required by paras. 3.2 and 3.3.

4.2.7 Ring Joint Flanges. The edge (periphery) ofeach ring joint flange shall be marked with the letter Rand the corresponding ring groove number.

4.2.8 Multiple Material Marking. Material for com-ponents that meet the requirements for more than onespecification or grade of a specification listed in Table1A may, at the manufacturer’s option, be marked withmore than one of the applicable specification or gradesymbols. These identification markings shall be placedso as to avoid confusion in identification. The multiplemarking shall be in accordance with the guidelines setout in ASME Boiler and Pressure Vessel Code, SectionII, Part D, Appendix 7.
